car analogy. imagine one car maker sells 80% of the cars. tomorrow they change how the gas pump works to only fuel their cars, but it fills a tank 5s faster! and they use the fact that they got 80% of the market already to force all gas stations to change to their pumps or lose their customers. now everyone buys their car because they can't even find a gas station with the universal pump anymore.

companies that move "faster than the standards" always do so under the guise of offering better products faster, but with the actual goal of locking in consumers to later enjoy a monopoly. see sony trying to always come up with a new media device, minidisc, memorystick, etc.
